I think an adjustment in the near future is certain. I think the idea around LD is that in the worst case scenario, it'll take any healer about 3 gcds to get the DRK out of WD.

In an ideal situation, invul skills are planned so healers can act accordingly, but we all know that this isn't always the case. While the exception should hardly ever be the rule, I do wonder if any flags have been raised on the dev end with the ratio of increased tank HP to the HPS from our healers.
